Failure Mode and Effect Analysis - an overview - ScienceDirect

The fail-safe mode of a pneumatic/spring valve is a function of both the actuator’s action and the valve body’s action. For sliding-stem valves, a direct-acting actuator pushes down on the stem with increasing pressure while a reverse-acting actuator pulls up on the stem with increasing pressure. Sliding-stem valve … See more Valve fail mode may be shown in instrument diagrams by either an arrow pointing in the direction of failure (assuming a direct-acting valve body where stem motion … See more It is important to note how the failure mode of a valve is often linked to its control action (air-to-open, air-to-close)844. That is, an air-to-open pneumatic control valve will fail closed on loss of air pressure, and vice-versa.

WebWhat is a control valve? The control valve is a valve installed in the fluid line to control the rate of fluid flow by varying the size of the flow passage in response to the control signal received by the actuator. The actuator in the control valve changes the position of the valve plug or disk. WebServo valves are a close relative of the proportional valve and are based on an electrical torque motor which produces a small deflection proportional to the electrical current through its coil. They commonly use feedback between the main and pilot spools to give precise control. A typical device is shown in Figure 4.40.This consists of a small pilot spool …

WebAnother very common problem found in control loops is static friction. Stiction is short for Static Friction and means that the valve internals is sticky. If a valve with stiction stops moving, it tends to stick in that position only. Then extra force is required to overcome the stiction. Even when the controller continues to change its output ...
